2. Server Configuration
Each system ran the same custom Linux UltraLight 2.6.24 kernel, with patches for FAST TCP and other TCP performance tunings built in.
Based on the different hardware combination, systems were grouped into four main categories:
A) 1U Servers with Fiber Channel Storage System + onboard Intel CX4 10GE NIC
8 of the 1U twin systems were outfitted with QLogic fiberchannel HBAs connected to Data Direct Networks storage system. Maximum read/write speeds between ??.
B) 1U Servers with Local Storage + Myricom10 GbE NIC (dCache Head Nodes)
4 of the 1U systems were outfitted with Intel Oplin single port 10GbE NIC and local storage with RAID-0 was used to source/sink data.
Maximum read/write speeds at 200MB/s.
C) 1U Servers with Local Storage with on board 10GE CX4 NIC (dCache pool nodes / individual systems)
20 of 1the U systems were configured with Myricom 10GbE NIC while the 4 hard drives were placed in RAID-0 configuration. Maximum read/write speeds at 200MB/s.
D) Sun Thumpers with Local Storage + Myricom 10 GbE NIC (disk servers)
The 4 x 2U servers were whitebox systems with Myricom 10GbE NIC and each system having 12 hard disks connected through Areca 1231ML RAID Controller and placed in RAID-0. Maximum read/write speeds at 500MB/s.
